Former Vice President Al Gore is venturing into a touchy topic, presenting his new solution to combat the buildup of greenhouse gases warming the planet.

At first he was just advocating simply improving technology to reduce fossil fuel emissions, but nowhe is advocating “empowering girls and women, by sterilizing all women under 25.”

Al Gore believes that the sterilization should be voluntary – at first – “women who are evolved will volunteer to be sterilized for the greater good for planet.” BUT, if women do not choose to sterilize themselves, Al Gore believes that the government should force women (under 25) to be sterilized.

“We have to take drastic steps to save the planet. There are too many people – we must take aggressive action or we will all be dead,” Gore said in a speech Monday in New York.

“When the population begins to stabilize and societies begin to make better choices – then women can have babies again.”

Gore’s thinking goes this way: If women are have access to “fertility management,” and if they have the power to act to save the planet by forgoing children, then the result would be stabilization of the global population.

As it stands now, demographers at the United Nations forecast that the world’s population will hit 7 billion later this year, march past 9 billion in 2045 and exceed 10 billion by the end of the century. Nearly all of the growth is expected to come in poor nations in Asia, Africa and Latin America.

Gore made his remarks at the eighth annual Games for Change Festival, a conference organized by those who want to promote the use of video games for social change.
